EXCLUSIVE! Vienna Girardi & Gregory Michael Are 100% OVER — He Totally Ignored Her At An Event Yesterday!

DISS! Vienna’s fling has fizzled – Gregory didn’t even acknowledge her presence when he ran into her in LA on Tuesday!

Poor Vienna Girardi! The Bachelor starlet’s rebound relationship with Greek star Gregory Michael is completely over – especially given that he’s taken to ignoring her in public!

“Gregory and Vienna are so over,” one of Gregory’s BFFs tells HollywoodLife.com exclusively. “She freaked him out. They haven’t seen each other for a while – but it seems like she’d still like to hook up.”

The insider says it was no coincidence that Vienna, 24, showed up at ESPN the Magazine’s ESPY Style Studio July 13 – moments after Gregory, 29, attempted to high-tail it out of the W Hollywood Hotel after catching wind of her arrival.

“He stepped off the elevator while she was walking in. He was on his phone and breezed right past her,” an eyewitness tells us. “Awkward!”

OUCH.

A second insider adds, “Gregory was flirting with anything that even resembled a girl. Doesn’t look to me like he was all that concerned about Vienna seeing it, either.”

Vienna, who has been fending off accusations that she cheated with ex-boyfriend Lee Smith while still engaged to former fiance Jake Pavelka, found comfort in the form of Chris Harrison after Gregory’s embarrassing cold shoulder. The Bachelor host made sure to protect Vienna, whose contract with ABC expires in two weeks, from prying eyes and said, “If you ever need anything, I’m here for you!”

It’s good to know that SOMEONE has her back!
